Ireland's Olympic boxer Aidan Walsh has been forced to withdraw from today's welterweight semi-final against British boxer Pat McCormack.
However, the 23-year-old is still guaranteed a bronze medal which he won in his quarter-final bout.
The Olympic Federation of Ireland says the Belfast fighter's been ruled out after a number of scans and medical reviews.
Team Ireland team leader for boxing, Bernard Dunne, said Aidan's achievement has been "incredible".
He said: “His performance throughout the tournament has been outstanding. And it is great to see him write his name in the annals of Irish sport.
"Just over two years ago we selected Aidan for his first major championship, and over the past few months that potential that we had identified has grown and developed into a world-class performance, that reflects greatly on the level of preparation he has put in ahead of these Games.”
It's the third medal for Team Ireland at the Games, following the gold won by rowers Fintan McCarthy and Paul O'Donovan and the bronze won by the women's four rowing team.
Elsewhere in the Games, Rory McIlroy has lost out on a bronze medal in golf following a tense third-place play-off with six other golfers.
There's another medal chance for Ireland later this morning when gymnast Rhys McClenaghan competes in the pommel horse final.
